AMQ学习笔记 - 17. 事务的测试

概述

对事务机制进行测试。

测试实例

测试实例 结果预测
发送正常 3条消息入队
发送异常 0条消息入队
接收正常 3条消息出队
接收异常 0条消息出队

测试分工

测试类 测试方法
TransactedProducer.java
- 测试发送		 sendNormal():void
- 测试“发送正常”
sendIntentional():void
- 测试“发送异常”
TransactedConsumer.java
- 测试接收		 receiveNormal():void
- 测试“接收正常”
receiveIntentional():void
- 测试“接收异常”

测试步骤和结果

1.测试发送

1.1.测试发送正常

测试步骤
  1. 在ActiveMQ管理页面，删除example.queue
    - 如果存在就删除
  2. 运行TransactedProducer#sendNormal()
    - 发送消息到example.queue
  3. 查看ActiveMQ管理页面
    - example.queue中有3条消息入队
测试结果
符合预期。

1.2.测试发送异常

测试步骤
  1. 在ActiveMQ管理页面，删除example.queue
    - 如果存在就删除
  2. 运行TransactedProducer#sendIntentional()
    - 发送消息到example.queue
  3. 查看控制台和ActiveMQ管理页面
    - 控制台有异常抛出
    - example.queue中入队消息0
测试结果
符合预期。

2.测试接收

2.1.测试接收正常

测试步骤
  1. 在ActiveMQ管理页面，删除example.queue
    - 如果存在就删除
  2. 运行TransactedProducer#sendNormal()
    - 发送消息到example.queue
  3. 查看ActiveMQ管理页面
    - example.queue中有3条消息入队
  4. 运行TransactedConsumer#receiveNormal()
    - 从example.queue中接收消息
  5. 查看控制台和ActiveMQ管理页面
    - 控制台打印出3条信息
    - 管理页面看到example.queue中的3条消息出队
测试结果
符合预期。

2.2.测试接收异常

测试步骤
  1. 在ActiveMQ管理页面，删除example.queue
    - 如果存在就删除
  2. 运行TransactedProducer#sendNormal()
    - 发送消息到example.queue
  3. 查看ActiveMQ管理页面
    - example.queue中有3条消息入队
  4. 运行TransactedConsumer#receiveIntentional()
    - 从example.queue中接收消息
  5. 查看控制台和ActiveMQ管理页面
    - 控制台打印出3条消息和异常信息
    - 管理页面看到example.queue中出队消息0条
测试结果
符合预期。
